If you ever wanted to belt out a tune, but not loud enough for your neighbors to hear, you might want to check out this downtown co-op that comes with its own soundproof recording studio and is listed for $2.79 million.

Voice lessons aren’t included, but they could be: The seller is voice coach to the stars Norma Garbo, whose clients include Taylor Swift. She also works with transgender people who want to learn how to talk like women or men.

Costly surgeries and hormone therapies can help people physically change genders, but their vocal chords largely stay the same, tying them to identities they are trying to shed. Garbo has been helping transgender folks make transitions since she helped a friend in 1981, according to reports.

Garbo first put her Greenwich Village unit on the market for $3.15 million in 2016.

The fifth-floor, floor-through home at 830 Broadway is 2,800 square feet and comes with its own key-locked elevator landing. Currently configured as a one-bedroom, two-bathroom unit, it can be rejiggered into a three-bedroom or more.

The loft features a large foyer, 12-foot barrel-vaulted ceilings, oversize windows, an open kitchen, a separate dining room and a laundry room.

The 1896 building was once a manufacturing warehouse.

The listing broker is Douglas Elliman’s Tracie Hamersley.
